Seeking the Ultimate in Marine Stealth: DARPA Pursues Quest to Finally Make Magnetohydrodynamic Drive a Practical Reality 

August 20, 2025 admin 0

Since the 1960s, academic, commercial and military researchers have attempted to realize a novel form of maritime propulsion involving no moving parts – no propeller, no drive shaft, no seals – just magnets and an electric current that silently propel a boat or submarine through water. It has been an elusive goal but tests are being conducted at Navy facilities this summer with an aim toward developing a practical, workable system.  […]

Alleima to Supply Coated Steel for Doosan Fuel Cell Interconnects 

March 12, 2025 admin 0

Swedish steel company Alleima will supply its Sanergy high-temperature pre-coated steel to Doosan Fuel Cell for its ramp-up to mass production of fuel cells for both maritime and stationary applications. The volume production is set to begin this year at a new manufacturing plant in Korea.

The Alleima material will be used for the interconnects, a key component in the fuel cell stacks. Alleima said in late January that it had received the order from Doosan which spans over two years for a total value of SEK 160 million. Deliveries were to start in the first quarter of 2025. […]

X-Division Spreads Helix e-Propulsion to More Markets & OEMs 

June 19, 2024 admin 0

Designers of high-performance products for e-mobility are getting to know the Helix brand, launched in 2022 to spread the electric propulsion technology of Integral Powertrain Ltd of the UK to more automotive and motorcycle OEMs while also positioning into aviation, marine and aerospace markets. From its roots in designing propulsion systems for motorsports, Helix has emerged as an established series manufacturer of the power-dense motors, inverters and e-powertrains that it develops. 

Its hallmark Scaleable Core Technology (SCT) platform has three product levels — stock, configured and custom. But its X-Division, focused on developmental projects in automotive, motorsport, aerospace and marine applications, leads the push into new electric powertrain designs. In two recent projects, Helix has designed a direct drive scaleable aerospace electric propulsion demonstrator and developed a revolutionary 650kW continuous output low-inductance motor for a new hypercar project. Both are based upon the company’s core technology in radial-flux motor topology and specialized inverters. […]
